A paintball squeegee is essential to carry with you on the paintball field to keep your barrel cleaned and shooting straight. There are a couple options to consider when it comes to paintball squeegees. You can choose from a straight shot, which is made of rubber and pulls through your barrel to clean it. A paintball swab is a popular choice among paintball players; a swab has a fuzzy end which allows you to clean your paintball barrel as well, leaving no unwanted dirt or grime left behind.
